Better to cut CO2 than complain about Paris deal

Independent, 12 January 2016:

I applaud everything in the letter from Professor Beckwith and colleagues apart from their faith in geo-engineering as a solution to climate change.

If you succeed in promoting the growth of plankton, then the oceans may well absorb more CO2, but this will result in greater acidification. Artificial whitening of clouds may produce a local benefit, but if extended globally it may well have a devastating impact on crop growth.

There is no easy techno-fix for climate change, and pretending otherwise delays the measures that are so desperately needed to address the problem: namely renewables, energy conservation, and a carbon tax that reflects the damage that fossil fuels wreak.
